A “charset” attribute on a “meta” element found after the first 1024 bytes.

Duplicate attribute “target”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “336px” for attribute “width” on element “img”: Expected a digit but saw “p” instead.
Bad value “280px” for attribute “height” on element “img”: Expected a digit but saw “p” instead.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Warnings:
